gen_bridge_metadata throwing error when processing headers

gen_bridge_metadata throwing error when processing headers

If I try running the command
`gen_bridge_metadata -F complete --no-64-bit -c '-DNDEBUG -I.' *.h -o
~/some/path/CocosDenshion.bridgesupport`
or any other command to generate bridgesupport files to process the
meta_data from some headers in a folder, I recieve this error:
/usr/bin/gen_bridge_metadata:60:in `basename': can't convert nil into
String (TypeError)
from /usr/bin/gen_bridge_metadata:60
I recieve this error regardless of the file, it could be something with
ruby... I dont know please help! Much appreciated!
